Web Shield - Script exclusions
Manage these settings at: Menu ▸ Settings (gear icon) ▸ Active Protection ▸ Web Shield ▸ Customize ▸ Script exclusions
The Web Shield protects you from harmful content on the Internet. Here you can specify websites to exclude from script scanning.
You may want to exclude specific web addresses, so you can access all content on those sites. Check the box and then enter the URL address you want to exclude.
This is only recommended if Avast blocks some content but you are sure that the site is safe. Please use caution.
